Thermia Duo is a variant of Thermia Diplomat TWS. The difference between them is that Thermia Duo has a separate hot water tank. With its low height, Thermia Duo is ideal for use with low ceilings.

Thermia Duo is intended to be supplemented with a separate hot water tank. An excellent choice if you need a lot of hot water or want to supplement an existing boiler. You can combine the heat pump and the boiler by using the boiler as an additional heater and the heat pump to produce heat and hot water.

The reliable, quiet scroll compressor is also in this heat pump. Thermia Duo has an integrated electrical heating element with three power stages (3, 6 and 9 kW) for additional heating when it is really cold outdoors.
